How to have the perfect fundraising Holiday Bazaar?

Members at my church are older and seem reluctant to change. Average age is 70. We need fun activities to bring back our younger population and bring in new members. Our church is literally dying out. We have become a poor church because of low enrollment and fived incomes. We need a shot in the arm. I thought a Holiday bazaar would be a great place to start. Something fun for our members and something that would entice ex-members back and new members from our community. The church is located in a poor section of the city. The actual membership used to be affluent which was a turn off to the neighborhood. I want the neighborhood to feel wecolme and feel like they belong.
